MITSUBISHI Uni Nano Dia Colour Lead (Blue) - 0.5 mm (Made in Japan)

Add vibrant blue colour, precision, and durability to your notes with the Mitsubishi Uni Nano Dia Colour Mechanical Pencil Lead Blue (0.5mm) — a premium Japanese stationery essential designed for smooth writing and clean corrections.

Made using Uni’s advanced Nano Dia technology, each lead is infused with microscopic nano-diamonds to create an exceptionally strong, dense core that resists breakage and delivers a consistently smooth writing experience. Despite being a coloured lead, it is erasable and rewrite-friendly, making it ideal for students, planners, teachers, and anyone who uses colour coding for organisation.

This Blue refill pack offers a crisp, clean shade perfect for technical diagrams, highlighting key notes, sketching, and study annotations — all in a mechanical pencil format. High-quality coloured mechanical pencil leads like this are rare to find in Australia, making this an excellent addition to any stationery collection.

Perfect for everyday study, exam preparation, architectural drafting, creative work, and colour-coded planning.

Product Availability

While we strive to keep our online inventory as accurate as possible, occasional discrepancies may occur due to clerical errors or other factors beyond our control. 

If an item you ordered is unavailable, we will notify you via your provided email or contact number. In such cases, you may choose an alternative product or receive a store credit. If you prefer, you can request a refund instead of a credit.

Pre-Orders or Back-Orders

Pre-ordering or back-ordering allows you to purchase items that are currently on-order. These items may be in production, in transit, awaiting delivery, or upcoming releases. Pre-order delivery times can vary between 3 to 12+ weeks, depending on the product's status.

If your order includes both in-stock and pre-order / back-order items, your order will be held until all items are available. Should you wish to receive the in-stock items sooner, the simpliest method is to create a separate order for pre-order / back-order items.
